There are three main types.

The first is typical commercial use, used in packaging and advertising. These require prior permission and paid use. Unauthorized use is an infringement and will result in administrative penalties and civil compensation. In serious cases, trademark and copyright crimes may also be involved.

The second category is typical personal use, such as building a snowman, cutting out drawings, entertaining yourself, sharing the Olympics, non-commercial activities. This is fair use, no infringement.

The third category is between personal and commercial use, such as making an emoticon or cutting your hair. Whether these are infringements must be specifically determined. If you make emoticons just for your own entertainment, it does not infringe. If you sell them or let others use them, it will dilute the trademark and affect the market of the rights holder, and it will still be deemed as infringement.
